Welcome to Mathebook.net an online Free Learning website full of fun. This website is fully interactive and will allow kids to practice and learn math with ease.
Our website is designed to help students of different grades, starts from Kindergarten, Elementary, Middle School and High School Math.
The goal of this website is to provide new education tools to teachers, parents and off course students who can benefit from it.
Mathebook.net has Online Tutorials as well as Downloadable pdf tutorials which one can save on computer and use later, even it can be used by teachers for home work purpose, as this pdf is editable and kids can e-mail the homework tutorials by e-mail back to Teachers. By using Downloadable Tutorials one can save the waste of paper and SAVE TREES, so we encourage you to be GREEN, and help mother nature to survive.
Online Tutorials has the score card which allows them to know how may answers were right or wrong. If the kid does not know the answer our intelligent tool will show the correct answer, it’s a learning curve !
Downloadable Tutorials are easy to use, but you will need Acrobat Reader to use this format ( which can be freely downloadable at www.acrobat.com ) One can save the work sheet, even if required take print out or just simply e-mail it to teachers and friends. In our downloadable section you will find several such pdf to download.
I am sure this website will serve and make life easy for kids, but we have not stopped here, we will continuously develop and further enhance the syllabus and will keep adding new features.
If you have a suggestion which can improve the user experience, share with us and we will work to incorporate on this website. That’s our Promise.

Mapillary
We believe a motivated person can capture the important and interesting details of any environment and neighborhood better than any single authority using cars can. There is no limit on the level of detail you can add.
How it works
1. Take photos with the Mapillary app while walking/biking/driving
2. Browse photos online at http://www.mapillary.com
3. Use the API to build stuff
Mapillary consists of a smartphone app, a website, and an API. With the app, you can take street level photos of roads, bike paths, buildings, and other areas relevant for mapping. These photos are uploaded to Mapillary's servers where they are processed and then made publicly available. The photos and additional data are accessible through an API for developers, app makers and mapping services to use.
________________________________________
The app
The app lets you take photos and upload them to the Mapillary service. You can also see photos taken near your location to help you find good areas to capture. For more details on how to use the app, see the using the app page. We are currently supporting iOS and Android phones.
Image processing
Once the photos are uploaded from your phone, they are processed with our computer vision stack. First they go through initial processing:
• Straightening. If possible, the photos are rotated to align horizontal and vertical features.
• Face blur. Faces in photos are blurred to protect the privacy of others.
• Removal of poor quality photos. Blurry photos, photos with too many people, large faces, low contrast etc.
• Matching between photos to estimate the camera position and movement to get better position, direction and all the nice transitions and navigation.
The photos that are not discarded are scaled to various sizes and made available through a public API. The originals are stored for later processing and more advanced analysis.

Introduction to IRIDIUM Networks
The Iridium System is a satellite-based, wireless communications network providing a robust suite of Voice and Data services to virtually any destination anywhere on earth.
With 66 satellites forming a cross-linked grid above the Earth, the Iridium system is the first low-earth orbiting system for telephone service. Only 780km (450 miles) high, these satellites work different from those at a much higher orbit (26,000km) in two major ways. First they're closes enough to receive the signals of a handheld device; and second, they act like cellular towers in the sky - where wireless signals can move overhead instead of through ground based cells.
Frequency Bands
Telephone & Messaging 1616-1625.5 MHz,L-band
Intersatellite Links 23.18-23.38 GHz, Ka-band
Ground Segment Links
Downlinks 19.4-19.6 GHz, Ka-band

How to create websites that use Google Maps/Earth to map information in a back end database
Professor Nitu,
I am happy to be named a friend! I hope you and your students find this work useful. Sometime later this year I will release code on how to create websites that use Google Maps/Earth to map information in a back end database. You can see an example at http://ctasgis02.psur.utk.edu/tokml.
Hopefully, I will complete an e-book on how to program for KML mapping engines, both desktop and web based.
Cheers,
Bruce Ralston

AFF Mapper - programe freeware
My colleague geogprof writes "I have released a program called AFF Mapper. This is
a Windows based package that was specifically designed for creating KML based mapping files from TIGER shapes and tables available from the Census Bureau's American FactFinder web page. While it was designed for these files, it can be used to create KML files for other shapes (that are in decimal degrees with NAD83 or WGS 84) and external attribute files. The resulting KML files can be viewed in several free mapping packages such as Google Earth and ArcGIS Explorer. To download a copy of
the program and the user manual, go to
[1]http://tnatlas.geog.utk.edu/downloadfree.htm. This is freeware, copy till you drop. Source code will be released at a later date." See also related stories below.

10 Thoughts for Someone Contemplating a Geospatial Career
by Jeff Thurston
All things change over time. This includes geographic information systems (GIS), computer aided design (CAD), global positioning systems (GPS), remote sensing, surveying and a wide array of geospatial technologies and applications. What I would have said to someone embarking on a spatially related career ten years ago would be different than what I would say today. Some things have changed dramatically, others in new ways and some minimally. Here is what I’d say today to someone contemplating a geo-career, in no particular order.
1) GNSS is an integration of GPS satellite systems. You can actually use a GNSS receiver today and get excellent results. If you thought one GPS was good, then 2 or 3 are going to really open your eyes. GNSS is going to revolutionise all we know about location based services. It will create a whole new class of professionals interested in position and navigation.
2) GIS is the de facto integrator of spatial information. Focus on it. Learn how all other technologies are spokes leading toward its integration. If you understand it as existing on a level equivalent to business systems then you will have the power to strategically drive new business applications and directions.
3) 3D is the future. It is not just about data though, it is also about visualisation. Start using the phrase ‘elegant solution.’ Pay attention to the concept of ‘Digital Cities.’
4) Sensing will increasing play a role that is supported through legislation. Data matters and numbers matter. Carbon credits become a currency, for example, and geotechnologies the stock exchange. I can’t say enough about understanding monitoring and it’s linkage to geospatial technologies. The current economic crisis will eventually lead to transparency and more of it.
5) Our concept of time is not well defined in spatial technologies. We can do scheduling well, but being able to understand ‘change over time’ is becoming more meaningful. It also relates closely to real-time versus static operating environments.
6) Remotely sensed imagery will become more widely used. More satellites equal more data. But other new satellites are now going to be providing information about CO2, NOx, global soil information and so on. Linking those satellite data to imagery will mean projects become larger, involve more people and take on the character of spatial data infrastructure (SDI).
7) I can’t help but think that we heading toward a major shift in energy use, production and utilisation. The way I see it, oil and gas together with wind, solar and biofuels etc. will require a balanced approach with feedback loops to operational building systems, social factors and other impacts. We’re about to enter a more holistically oriented and managed energy scenario. This goes back to integration - GIS.
8 ) Think communities. Better and more efficient housing located near better and more efficienct tranportation systems.
9) Learn to write. Develop communication skills. Many of our colleagues tell me, “I wish I could write.” It will help you to share and collaborate on all the integration going on.
10) Find a mentor. A person who would agree to work with you as your career develops and who you would invest a time commitment toward. It can be daunting when starting out and many people can help you to get up to speed quickly. If you want a mentor, then simply ask them. But know what you are asking and be prepared to listen.

Istoria altfel
,,Cucerirea normanda a Angliei este reprezentata prin imagini pe „tapiseria de la Bayeux“, realizata in secolul al XI-lea, la curtea normanda a lui Wilhelm Cuceritorul si atribuită reginei Mathilde (1031 - 1083). Aceasta este o bucata de panza lunga de aproximativ 70 m si lata de circa 0,50 m pe care sunt brodate cu fire de lana in opt culori 58 de scene, incluzand peste cinci mii de personaje care au participat la evenimentele din 1066. Din Tapiserie rezulta ca au fost doborate paduri intregi pentru construirea si armarea a sapte sute cinzeci de corabii care trebuiau sa transporte, dupa calculele strategilor vremii, intre 12.000 si 15.000 de oameni peste Canal. Flota a fost gata la inceputul lunii septembrie 1066, dar inca cinsprezece zile, vanturi contrare l-au retinut pe Wilhelm in Normandia''(ALTERMEDIA.INFO)Cu HISTORIC TALE CONSTRUCTION KIT te distrezi imaginand povesti medievale !
